In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to increment all negative numbers by 1 and decrement all positive numbers by 1. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {12, 21, -31, -14, 56, 16, 17, -18, 9} After updating the array element are: -30 -17 -13 8 11 15 16 20 55 (sorted) Instance-2 Suppose the original array is {19, ...

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to delete or eliminate the odd numbers present in the array and print the even array. Note − The array must be an integer array. A number is said to be an odd number if the array is not divisible by 2. In this article, you will see how to remove odd numbers from an array by using Java programming language. Let’s explore. To Show You Some Instances Instance-1 Suppose the original array is ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the array elements which are present in the odd position in an array and print them. A number is said to be even if it is divisible by 2 else it is called an odd number. Note − The array must be an integer array. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is ... Read More

In Java, Array is a non-primitive data type which stores values of similar data type. As per the problem statement we have to detect which element is repeated maximum times in an array for maximum number of times and print its frequency. An array can contain duplicate values as well. So, the number of times an element is present in an array, that is called frequency of the element in the array. And the element whose frequency is more that is the most frequent element in the array. Let’s see how we can do it by using the Java programming ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the union of two arrays. Union refers to joining together whereas union of arrays refers to the new array combining all unique elements from the input arrays. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the first array is {0, 3, 5, 6, 9, 1}. And the second array is {1, 2, 6, 10, 8, 7}. ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the element which is present in the middle of the array. If the array contains odd number of elements, then you will get one element present at the exact middle of the array. If the array contains even number of elements, then you will get two elements present at the middle of the array. In this article, you will see how to get the middle element of an array by using Java ... Read More

In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the largest palindrome in an array. A number is said to be a palindrome number if after reversing the same number it is equal to the original number. Let’s explore the article to see how it can be done by using Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {857, 232, 1996991, 54545} After finding the largest palindrome of an array the result will be ... Read More

In Java, Array is a non-primitive data type which stores values of similar data type. As per the problem statement we have to find the frequency of each element i.e how many times each element is occurring in an array. Let’s see how we can do it by using the Java programming language. To Show You Some Instances Instance-1 Suppose the original array is {21, 10, 26, 21, 10, 33, 33, 20, 10, 21} After finding the frequency of each element of an array the result will be − Element | Frequency ------------------------ 21 | 3 10 | 3 ...
